Title: Improvements in and relating to the manufacture of copper phosphide
IPC: C01B25/06
Filed: 1945-08-09
Abstract: Copper phosphide is obtained by treating cupric or cuprous oxide with phosphoric acid in the presence of carbon under conditions such that reduction is effected and the other products of the reaction separate by volubilization.  According to an example, cuprous oxide is mixed with phosphoric acid and charcoal to form a homogenous and porous paste which is heated at 1100-1200 DEG  C. in a graphite crucible. Preferably, the amount of carbon used is sufficient to form some carbon monoxide in addition to carbon dioxide.

Title: Improvements in and relating to rotary pumping apparatus
IPC: F23K5/14
Filed: 1935-07-26
Abstract: 450,197. Rotary pumps; centrifugal blowers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. July 26, 1935, No. 21295. Convention date, July 26, 1934. [Classes 110 (i) and 110 (ii)] A pumping apparatus for supplying oil and air to a burner heating a boiler which may be of the type described in Specification 441,893, [Group XI], comprises a sliding-vane type of pump 21 for pumping air and oil supplied separately, and a blower with rotor 28, both rotors being mounted on a shaft 23 driven by an electric motor 20. The various oil and air inlets for the pump, surge chambers, and delivery passages, are contained within the pump casing 21 and the end covers 24, 25. Oil enters through a pipe 45 to a conduit 46 which feeds a surge chamber 48, and also the pumping chamber, the latter by way of a port 49 which co-operates periodically with two diametrical-opposite grooves in the pump rotor 27. The port 49 is shaped as an arc in the cover 24. Air enters the working chamber through an arcuate port in the cover 24 by way of two surge chambers separated by a restricted orifice. Oil is sucked into the working chamber before the air inlet is uncovered by the rotor 27, when the oil inlet is closed. The mixture is delivered to a separating chamber, the oil drops into the tank 29, and the air passes into the tank through a separate port. Compressed air is delivered to a burner nozzle from the tank 29, the outlet being regulated by a byepass valve which connects the outlet with the incoming air surge chamber. Oil under pressure is discharged through a passage 77, a surge chamber 78, and a passage 80 leading to the nozzle. Air bubbles collecting in chamber 78 are forced through a restricted passage 79 leading to the incoming air surge chamber. Strainers 47 and 83 are fitted in the system. The level of the oil in the tank 29 is regulated by a byepass valve 86, connecting the tank with the surge chamber 48. The valve is controlled by a float 85 secured to a shaft 90 about which the float pivots. Oil for lubricating and seating purposes passes up a passage 95 to a channel 96 and is fed into the pumping chamber. Surplus oil is deflected by a cone 98 into a channel 56 from which the air inlet port leads to the pump. The blower, which supplies air to the furnace, has a casing 22 mounted in a felt washer 103, which supports a plate 101 holding down the stator 100 through bolts screwed into the pump casing. Leakage from the tank 29 is prevented by a ring 30 pressing up a lip 110, initially conical, against a washer 111, by means of bolts. These bolts are mounted on springs to damp out noise and vibration from the pump, which is thus mounted upon the boiler being supplied with fuel. The pump rotor is in two segments separated by the vane slots, the segments being riveted together.

IPC: B01J8/44
Filed: 1952-08-26
Abstract: <PICT:0740974/III/1> A fluidized-bed furnace has a grid through which gas is supplied to the fluidized bed, means being provided for controlledly varying the cross-sectional area over which the gas enters the bottom of the bed.  As shown in Fig. 1 gas is supplied through individually-controlled pipes 22, 23, 24 to respective concentric sections 25, 26, 27 of a windbox located beneath the grid 20.  In modifications, the grid is in the form of concentric steps. In a further modification gas is supplied through a single pipe to an unsectioned windbox and the effective area of the grid is reduced by affixing annular brickwork to the upper side thereof.  In an example it is stated that 50 tons of finely-divided pyrite of 48 per cent sulphur having a particle size less than 65 Tyler screen mesh and averaging 50 microns requires a reactor having an inside diameter of about 16 feet, air being supplied at 230 c.f.m. per ton of feed and the space velocity being 1 foot per second.  If the size of the material is increased to less than 6 Tyler mesh and average size 600 microns to maintain the same capacity and gas strength a reactor diameter of 6 1/2 feet is required, and in the reactor described all the gas would then be supplied through conduit 24, the space velocity being 6 f.p.s.  The capacity of the reactor and the sulphur and gas quantities would remain unchanged and the exit gas strength would remain constant at about 14 per cent SO2.  The reactor according to the invention may be applied to any reaction carried out under solids-fluidizing conditions.

Abstract: 422,065. Valves. BRUCE, J., 31, Deyncourt Gardens, Upminster, Essex. Sept. 1, 1933, No. 21460. [Class 135] A valve device comprises two independently actuated valves arranged in a single casing and adapted to control a single passage-way, the actuating means being interlocked so that one valve must always be fully opened before the second valve can be opened and the second valve fully closed before the first valve can be closed, so that the first valve is protected against scoring. The two valve spindles f, g project in opposite directions from the casing and carry at their inner ends oscillating disc valves d, e, co-operating with seats b, c. The spindle f is fitted with a disc m having a cam surface n extending 180‹ round its periphery which co-operates with a spring controlled locking bolt slidably mounted in guides carried by a bracket secured to the casing. The upper end of the bolt engages a hole t in a plate a secured to the spindle g to hold the valve e closed until such time as the valve d is opened, when the cam is rotated to permit the withdrawal of the bolt. While the valve e is open the end of the bolt is below the plate s, thus preventing the rotation of the cam plate. The two plates m, s, have projections adapted to co-operate with pillars on the casing to limit the movements of the valves. According to the Provisional Specification the required sequence may be obtained by means of a quadrant or disc form of valve, operated by a single spindle, and provided with a port which by arcuate movement covers and uncovers the inlet and outlet valve seating apertures. Further the required order of opening and closing may be secured by vanes moved transversely across the fluid conduit by a single spindle.
